Users have reported that the new voice calling feature is enabled in the latest build of the WhatsApp Messenger, which is now available for download for Android devices on Google Play (version 2.11.561).

However, do note (as we mentioned in the earlier article today), the feature will not be activated until you receive an ‘invitation call’ by a person who already has the functionality. Once you receive the first VoIP WhatsApp call, you will be able to further pass the ‘contagious’ feature on to others on your contact list through a simple voice call.
Now for the steps involved:

#2. Request another WhatsApp user you know with the voice calling feature activated to call you via WhatsApp.

Once you receive the call, you will find the WhatsApp voice calling feature activated on your phone. You should be able to see a new ‘Calls’ tab to the left of the Chats and Contacts tab on the WhatsApp home screen.

A user in Dubai who downloaded the app and received the invitation call from a family member in India claims her WhatsApp calling is now activated, and did call us up through the app as verification.
